For AAA model induction, 7 studies established AAA model with elastase [15, 16, 21–25], 6 studies with Ang II [16, 27, 28, 30, 31, 35], 3 studies with xenograft techniques [32–34] and 2 studies were established with the combination of elastase and CaCl2 [29, 36]. Here, AGT is linked to triple-A syndrome.
